About Diablo Auto Specialists

About Us | Diablo Auto Specialists

Established in 1979 as one of the first Independent Honda Repair shops in the area, Diablo Auto Specialist quickly gained a following. People spread the word that our outstanding customer service and technicians repaired and serviced cars better than the dealerships. Over the years, we added educated technicians to our Honda specialist team, and now Diablo Auto Specialists are qualified to service all Japanese makes and models.

In September 2002, Tim and Cathy bought the business. By taking over the shop, they fulfilled their lifelong dream of serving the community with a superior automotive shop. Through hard work and careful planning, Diablo Auto Specialists has grown. We now service most Import and Domestic vehicles. We dedicate our time to hiring the most qualified and talented staff, and invest in new technology and constant training and education. We are always looking for new ways to improve the business.

Diablo Auto Specialists is proud to have an ASE Certified staff. We are also members of ASCCA (Automotive Service Council of California) & ASA (Automotive Service Association) We have been a Certified GREEN Business in Contra Costa County since 2005 & the Walnut Creek Chamber of Commerce named us 2010 Business of the Year.
We appreciate all of our customers and advocates who have made us the success we are today.
